Symmetra PX 250/500: What happens when EPO is activated?

Issue:
Symmetra PX 250/500; What does the EPO (Emergency Power Off) trip
 
Product line:
Symmetra PX 250/500
 
Environment:
All serial numbers
 
Cause:
What occurs when the EPO on a Symmetra PX 250/500 button is engaged?
 
Resolution:
When the EPO is activated, UPS output breaker Q2 and the battery breakers are tripped. The Power Modules (inverter) and if in Static Bypass operation will the UPS turn off

Is there a disposable lid for the 252/32/1 junction box?

No, unfortunately there is nothing available.

What is the part number for a conduit j-box with 3 x 50mm entries?

The part number for a conduit j-box with 3 x 50mm entries is - 252/50/3

Symmetra PX 250/500; AP9635; Flood of RTC Time adjusted values in the logs

Issue:
Flood of RTC Time adjusted values in the logs
 
Product line:
Symmetra PX 250/500 with AP9635
 
Environment:
All Product models, all serial numbers
 
Cause:
When 2 Network Management Card (NMC) are installed in the UPS and set to NTP (Network Time Protocol), they will fight for control of the time to the display and continually send info alerts on RTC Time Adjusted.  In the chart below you will notice in column 5 there are two different numbers 2 & 4, which would indicate that there is 2 NMC in the UPS one in position #2 and the other in position #4.  This is the indicators that 2 NMC are fighting to provide time through NTP
 
46934 Info IM internal memory for storing configuration settings is OK IO enclosure level 3 pos E    02-26-2015 17:12:53 006
46933 Info RTC Time adjusted value Parallel UPS 1  2   02-26-2015 17:12:53 000
46932 Info RTC Time old value   2   02-28-2015 17:12:57 446
46931 Info IM internal memory for storing configuration settings is OK IO enclosure level 3 pos E    02-28-2015 17:12:49 006
46930 Info RTC Time adjusted value Parallel UPS 1  4   02-28-2015 17:12:49 000
46929 Info RTC Time old value   4   02-26-2015 17:12:44 548
 
Resolution:
Set only one of the NMC to NTP
 

 

Symmetra PX1-PX2; What happens when PX1, PX2 and 250/500K PX is EPO'd

Issue:
What happens when PX1, PX2 and 250/500K PX is EPO'd
 
Product line:
Symmetra PX
 
Environment:
All models, all serial numbers
 
Cause:
This document describes how the Symmetra PX reacts to the EPO circuit being activated. Emergency Power Off (EPO) is the capability to power down a piece of electronic equipment or an entire installation, in the case of an emergency, from a single point by activating a push button.
 
For 20K, 40K, 80K PX:
If the EPO circuit in the Symmetra PX is activated the System Enable Switch turns to the off position, the DC Breaker in the Main Frame or in the XR Frame (80kw units only) also switches to off. Mains feed CB will be tripped on ISX PDU. There is no power on the output of the XR Battery Frames or on the output of the Symmetra PX UPS.
 
An EPO event is not recorded in the Event Log.
 
For 100K PX:
Only the Battery CBs on XR frames will be tripped. Customer would need to have optional shut trip on Upstream CB to turn off input power to UPS.
 
For 250K/500K PX:
All Battery CBs on battery frames and Q2 will be tripped
 
Resolution:
Reset EPO switch and follow proper procedures to restart UPS
 

Symmetra PX 250/500 Battery to Power Module Ratio

Issue:
Symmetra PX 250/500 Battery to Power Module Ratio

Product line:
Symmetra PX 250/500

Environment:
All Product models, all serial numbers

Cause:
Required battery to power module ratio for a Symmetra PX 250/500

Resolution:

Ratio between numbers of battery shelves and power modules (PM)

Maximum recommended discharge level on the batteries used for Symmetra PX 250/500 is 3CA, where CA means the current (Amps) by which the battery is charged or discharged divided by its Amp-hour (Ah) rating.  The 250kW runtime ratio is 10 PMs to 16 battery shelves resulting in a ratio of 1.6 battery shelf per 1 PM. Need to always round up the number of shelves

Results if ratio is not maintained

In some situations, the Power Modules will attempt to draw power from the batteries and if the ratio is not observed, you will potentially clear fuses in the battery modules and (less likely, but it happened before) burn traces on the battery backplane boards due to the DC inrush current.
